Latas Patent NQ. 90,066, dated May 1s, 1869.

iMPRovED PRooEss or nsmcrr` UNMASHEDV INDIAN coRN 1N BREWING REER, ac.

The Schedule referred to in` these Letters Patent and making part of the same.

To all whom it may concern Be it known that I, NIGHOLAsBAUMANN, of Kalamazoo, in the county of Kalamazoo, State of Michi-V gan, have invented a new` and improved Mode of Applying Uumashed Indian Oornrin the Manufacture of Beer; andI do hereby" declare that thefollowing is a full and exact description thereof, reference being hadv to the accompanying drawings, and tothe letters of reference marked thereon.

` rlhe nature of my invention consists in lproviding two mash-.tubs A and B, Figure I-representing a perspective view, A B, Figure II, representinga transverse "section, and A B, Figure III, representing va y plan.

The tub B,Fig.1,may beconstued smaller in size than the tubv A, andis placed so that its bottom l is aboutffour inches higher than'the top of the larger gone.'

Each tub has'its own mash-machine, and thecontents of the smaller one, B, may be let oi through the pipe O, Fig-.1, into the :lower one, A.

Steam may be conveyedv hrongh the pipes 'D and E, Fig. I, D and E, Fig. II, D and E, Fig. III, into both tubs, stop-cocks being provided, so as to permit each tub to be supplied with'steam independently of the other. l

The pipe D, Fig. I, ends where it enters the lower part ofthe 4tub A, and has but a single opening.

The pipe E, leading steam to Athesmaller tub B, is

V; continued into the inside'of the same, in the `form of a spiral or circular pipe, perforated on the inner sides p with a large number of small holes, throughwhich `the steam is driven kinto the contents of the tub.

v To enable others skilled in the art to use my invention, I will proceed to describe the process.

` While commonl barley-mash is being made in the' large tub, A, Fig. I, the smaller tub, B, is lled to half its height with water, and steam -isthen introduced through the pipe E E E, Fig. III,'until the water 'reaches a temperature of 160.0 to 1165O;`then Indian-corn meal is put into. the water, (in quantity equal to'that of malt used in the larger tub A,) and thev mash-machines are putin motion.` l l The stop-cocks for the admission of steam being open, the steam is continually driven from the inside spiral' pipe E E, Fig. III, toward the centre of the tub, causing a bubbling of the mixture, especially in the centre of the same. After a time, the bubbling will become stronger near the inner sides of the tub. The corn meal is now entirely dissolved, the liquid clear like a dissolution ofi sugar. It is now the proper moment to mix the contents of this tub B with the Y equal quantity of malt, prepared, in the mean time, in

`the larger tub A. f

The stop-cock F, Figi I, is now opened, and the tub B is emptied \throu h the pipe C into the larger tub A, under a continua movement'of the mash-ma-AA chines in each tub. Both iluidsbeing` thus completely mixed, produce an excellent heer.

It is known that malt is able to transform a larger quantity of starch into sugar than that which is con-- -tained in the barley itself, andit is not anew thing to apply unina-shed Indian corn in the manufacture of beer; 'but diculties have arisen everywherev in endeavoring thoroughly to mix the unmashed corn with the mash, and thuslto utilize the whole transformingpower ofthe malt.

The object of the abovedescribed process is to overcome 4these diiculties.

What I claim as my invention, and desire to secure and B, for the purposes set forth and described.

NICHOLAS B/AUMANN.
